See the DAP help page on how to choose your access level for your data collection record in the DAP Protect your Data
Not all data needs to be made publicly available to be stored in the DAP. Some sensitive data will be only available to specific parties. And a project does not have to be final and ready for publication. A Data collection record in the DAP may start with a less open access then move to a more open access level during the course of a research project when the research is ready for publication via a simple update.
